To all whom it may concern:

Be it known that I,- JAMss MoDANmL, a citizen of the United States,residing at St. Louis Missouri, have invented a certain new and usefulImprovement in Hose Coupling and Clamping Devices, of which thefollowing is a full, clear and exact description, such as will. enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to hose couplings, and has for its main object toprovide an efficient, means of novel construction for clamping a hosetightly to a coupling nipple or to a device mounted in the end of thehose.

Another object is to provide a hose coupling or clamping device thatcomprises a sectional hose-clamping means that completely surrounds thehose and whose exterior is screw threaded, and an adjustable taperedsleeve that is adapted to be screwed onto said clamping means so as tocause the parts or sections of same to clamp the hose tightly to thenipple or member inserted in the end of the hose. And still anotherobject is to provide a hose-coupling or clamping device which is sodesigned that the natural tendency of the operator to turn 'or twist thehose with relation to the nipple or object inserted in the end of thehose results in causing the hose to be clamped more tightly to saidnipple or object.

Other ob'ects and desirable features of my invention will be hereinafterpointed out.

Figure 1 of the drawings is a view partly in elevation and partly insection of a hosecoupling constructed in accordance with my invention;Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1;Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 1;Fig. 4 is a side elevational view of a device embodying my invention forclamping a hose to a nozzle or other object that is inserted in the endof the hose; and Fig. 5 is a perspective view of one part or section ofthe hose-clamping means ofthe device.

Referring to Fig. 1 of the drawings which illustrates a deviceconstructed in accordance with my invention for coupling two sections Aof hose together, 1 designates a coupling nipple that is inserted in theends of both sections of hose, 2 designates a plurality of form.

members that form a tubular-shaped clamp mg means for each section ofthe hose, and 3 designates sleeves that cooperate with the members 2 toforce said members into snug engagement'with the sections of the hoseand thus cause the hose to be clamped tightly to the coupling nipple 1,it being, of course, understood that the members 2 and sleeve 3 thatcooperate with one section of the hose are separate and distinct fromthe members 2 and sleeve 3 that. cooperate with the other section of thehose. As shown in Fig. 5, each of the members 2 consists of a segment ofa cylinder, and in the embodiment of my invention herein shown, four ofsaid members are usedjto form each of the tubular-shaped hose-clampingmeans of the device. The four members 2 that constitute each of saidtubular-shaped clamping means have mterlocking teeth or portions 4 thatprevent said members from moving longi tudinally with relation to eachother, but said interlocking teeth 4 are so designed that the members 2can move radially with relation to the coupling nipple 1 so as to varythe diameter of Ithe lubular shapcd hose-clamping means which themembers 2 Screw-threads 5 are formed on the exterior of the members 2,and the sleeve 3 that cooperates with each set of members 2 isscrew-threaded on its inner side and tapered longitudinally so that themembers 2 will clamp the hose tightly upon the 'coupling nipple 1 whenthe sleeve 3 is screwed onto the members 2, as shown in Fig. 1, the

operation of screwing up the sleeve resulting in a gradual tightening ofthe members 2, or, in other words, operating to gradually reduce thediameter of the tubularshaped clamping means formed by the members 2. Inorder to prevent one set of members 2 from turning when theircooperating I sleeve 3 is being screwed onto same, I have provided themembers 2 with substantially T-shaped devices 6 thatinterlock with adisk 7 arranged on the coupling nipple 1 at approximately the center ofsame, as shown in Figs. 1 and 3.

In assemblin the parts of my improved hose-coupling evice, the T-shapedparts I} on the hose-clamping members 2 of one set are arranged instaggered relation with the parts 6 of the hose-clampin members of theother set, as shown in Fig. 1, and the sleeves 3 are thereafter screwedonto the members 2 so as to cause said members to clamp the hose tightlyupon the coupling nipple, and in view of the fact that one set ofclamping members 2 are interlocked with the other set of clampingmembers, through means of the disk 7 there is no tendency for one set ofclamping members 2 to turn when their cooperating sleeve 3 is beingscrewed onto same.

In Fig. 4 I have illustrated a device embodying my invention forclamping a hose onto a nozzle or other member 1*, said device comprisingonly one set of segmentalshaped clamping members 2 and a cooperatinginternally tapered sleeve 3*, the disk 7 of said device which isinterlocked with the members 2, being grasped by one hand of theoperator when his other hand is used to screw up the sleeve 3".

A hose-coupling or clamping device of the construction above-describedwill bind a hose tightly to a coupling nipple or to an object insertedin the end of the hose owing to the fact that it comprises atubularshaped hose-clamping means that completely surrounds the hose andwhose inner diameter is reduced gradually during the operation ofapplying the device. The device can be applied or removed quickly, andas it comprises a rotatable sleeve that is mounted on the end of thehose adjacent the nozzle or nipple inserted in the hose, the

natural tendency of the operator is to screw up said sleeve and thusclamp the hose more tightly when the hose is being used. Consequently,my improved device is particularly well-adapted for use on pneumatichammers and similar tools that require a perfectly tight joint betweenthe hose and the nozzle or nipple of the tool.

Having thus described my invention, what I claim as new and desire tosecure by Letlongitudinal edges with laterally projecting interlockingportions, an internally tapered sleevecooperatin with each set ofclamping members and a apted to be screwed onto same so as to force themtightly against the hose, a device loosely mounted on the nipple betweenthe ends of the sections of hose, and portions on both sets of clampingmembers ,that'interlock with said device so as to prevent one set ofclamping members from pulling longitudinally away from the other set.

2. A hose-coupling device, comprising a coupling nipple, a pair oftubular-shaped hose-clamping means, each of which is composed of a setof interlocking segmentalshaped members that completely surround thehose with which they cooperate, an internally tapered sleeve adapted tobe screwed 7 onto each set of members so as to force them tightlyagainst the hose, substantially T-shaped devices on the inner ends ofsaid segmental-shaped members, the devices on one set of members beingarranged in stag gered relation to those on the other set of members,and a disk at'approximately the center of the nipple that interlockswith said T-shaped devices.

In testimony whereof I hereunto aflix my signature in the presence oftwo witnesses, this twenty fourth day'of February 1913.
